Ionic app can not access internet

My App runing well on browser, but it is not able to access internet from emulator and device

I have add
< plugin name=“cordova-plugin-whitelist” spec="~1.2.0"/>
< access origin=""/>
< allow-intent href="http://
< allow-intent href="https://
< allow-navigation href="
" />

also change
< meta http-equiv=“Content-Security-Policy” content=“default-src *; style-src ‘self’ ‘unsafe-inline’; script-src ‘self’ ‘unsafe-inline’ ‘unsafe-eval’”>

but still not able to access internet
